Their paper in the Journal of Family Psychology is entitled 'The association between daily stress and sexual activity" (vol 24(3), June 2010, 271-279. doi: 10.1037/a0019365).
The researchers used 103 female students in their study.
The women completed questionnaires over a three-month period, along with filling out diaries on 12 separate occasions -- each just before a major examination.
According to the abstract to their paper, 'Findings suggest that higher self-reported stress in daily life was associated with lower levels of sexual activity and satisfaction and a decrease in relationship satisfaction.'
The researchers state that their study is ''¦ one of the first to examine the covariation between self-perceived stress and daily sexual activity within a time period of 3 months by collecting data on stress, sexual activity, sexual satisfaction, and sexual fulfillment as well as individual and dyadic coping.'
And also they said, ''¦ dyadic [couples] coping was positively associated with sexual outcomes but did not moderate the association of experienced stress and sexuality.'
